摘要: 本文利用轉(zhuǎn)動變換推導(dǎo)出五種典型放大電路的負(fù)阻條件;利用負(fù)阻效應(yīng)特有的復(fù)合振蕩現(xiàn)象取得了擴(kuò)展振蕩頻帶、增強(qiáng)振幅的效果;從而表明,在反饋振蕩器與負(fù)阻振蕩器之間存在可供實(shí)用的第三種振蕩形式。

Abstract: In this paper, making use of the rotatory transform, the negative resistance condi-tions of five typical amplifiers are determined. Using the phenomena of combination oscillation existing only in the negative resistance effect, we obtained the results of spreading the oscillatory band and of amplifying the amplitude. Thereby it indicates the fact that there is a third oscillatory type oscillator, between feedback oscillator and negative resistance oscillator which has actual usability. -
